Barriers to self-monitoring of blood glucose among adults with diabetes in an HMO: a cross sectional study

Unveiling the interplay between rational, psychological and functional factors in continuous glucose monitoring early adoption: Novel evidence from the Dexcom ONE case in Italy

BACKGROUND

The escalating prevalence of diabetes, with its multifaceted complications, poses a pressing challenge for healthcare systems globally. In response, the advent of continuous glucose monitoring (CGM) systems, offering technological solutions for daily diabetes management, presents significant opportunities. However, the widespread adoption faces several barriers, linked both to the technological configuration of the devices and to the psychological dimension of patients. Therefore, this study aims to apply and test a theoretical model that investigates the antecedents of the intention to use Continuous Glucose Monitoring systems.

METHODS

The research model was built to unveil the impacts of psychological factors, functional components and rational constructs derived from the Technology Acceptance Model (TAM) on CGM systems sustained adoption. To ensure the comparability of results, we have collected data from people who had used Dexcom ONE Dexcom (San Diego, CA) for the first time for at least one month. Employing Structural Equation Modelling (SEM) techniques, the hypothesized relationships among constructs were assessed.

RESULTS

The analyses confirmed the positive correlation of rational factors to the Intention to Use. Subjective Norm, intended as the physicians' influence, is positively correlated with the Perceived Usefulness. Trend Arrows, albeit being negatively correlated with Perceived Usefulness, have a positive correlation on Perceived Ease Of Use, reinforcing its mediating effect towards Perceived Usefulness. Among psychological factors, Trust in the CGM technology positively correlates with Intention to Use. Health Literacy is negatively correlated to the Intention to Use.

CONCLUSIONS

These findings contribute to theoretical and managerial understanding, providing recommendations to enhance the adoption of CGM systems like Dexcom ONE.

Design and validation of a Questionnaire on the factors influencing self-care behaviors in patients with Multiple sclerosis (QFASMS)

BACKGROUND

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). Since MS does not have a definitive cure, individuals affected by it need to adapt and coordinate with their chronic illness in order to fulfill their duties and responsibilities. The first step in helping patients to better care for and manage their illness is to engage in self-care behaviors. This study was conducted with the aim of design and validation of a questionnaire on the factors influencing self-care behaviors in patients with Multiple sclerosis.

METHODS

This cross-sectional study was conducted on Multiple sclerosis patients in Iran in 2023. The age range of patients varied between 22 and 52 years. Having MS disease, passing one year of the disease duration, living in Mashhad city, having informed consent to participate in the study and not completing the questionnaire were the entry and exit criteria of the study.

RESULTS

This study was conducted on 500 patients with multiple sclerosis. Based on the results of psychometrics (face, content and construct validity), the number of questions was reduced from 120 to 47 questions and 73 questions were eliminated. Finally, the questionnaire was approved with 47 questions and 4 subscales of understanding the symptoms of the disease (9 questions), tendency to conscious and targeted care (21 questions), laziness in care (8 questions) and tendency to receive therapy services (9 questions). Cronbach's alpha and McDonald's omega index for all questionnaire questions were 0.877 and 0.881, respectively.

CONCLUSIONS

Based on the results of this questionnaire, 47 questions and 4 subscales can be used to measure the factors influencing the adoption of self-care behaviour's in patients with multiple sclerosis.

The relationship between personality profile and self-care among patients with type 2 diabetes

Background

As a chronic disease, diabetes needs special self-care behaviors until the end of life. Personality traits are considered to be effective psychological factors in controlling diabetes and self-care in patients with diabetes. The present study was conducted to determine the relationship between personality profile and self-care among people with type 2 diabetes.

Methods

In this descriptive-correlational study conducted in 2021, 160 patients with type 2 diabetes referred to the diabetes clinic of Imam Khomeini Educational and Medical Center in Ardabil were selected by convenience sampling method. The data collection tools included the Diabetes Self-Care Activities questionnaire (SDSCA) and the short form of the Millon Multi-Axis Clinical Test (MCMI-3), which were completed through interviews with patients. Data were analyzed by SPSS software using descriptive statistics (mean, SD, and frequency) and inferential statistics (Pearson correlation coefficient and linear regression).

Results

Based on the results, apart from the obsessive personality disorder, which had a positive relationship with self-care behaviors, a significant negative correlation was observed between schizoid, avoidant, depressed, dependent, antisocial, self-harming, borderline, and paranoid personality disorders with self-care behaviors (p < 0.01).

Conclusion

The results showed that there is a significant negative relationship between personality profile and self-care status of patients with type 2 diabetes. In other words, a person's personality profile can predict self-care behaviors. Accordingly, personality traits can be considered as one of the influencing factors on self-care in the educational programs of diabetic patients. Holding educational classes to empower patients using psychological interventions and teaching effective solutions can be an effective step toward increasing the level of mental-physical health and self-care of patients with type 2 diabetes.

When Less Is More: Identifying Patients With Type 2 Diabetes Engaging in Unnecessary Blood Glucose Monitoring

This study examined whether certain patient characteristics are associated with the prescribing of self-monitoring of blood glucose for patients with type 2 diabetes who are not using insulin and have well-controlled blood glucose. Against recommendations, one-third of the patient sample from a large health network in North Carolina (N = 9,338) received a prescription for testing supplies (i.e., strips or lancets) within the prior 18 months. Women, African Americans, individuals prescribed an oral medication, nonsmokers, and those who were underweight or normal weight all had greater odds of receiving such a prescription. These results indicate that providers may have prescribing tendencies that are potentially biased against more vulnerable patient groups and contrary to guidelines.

Predictors of self-monitoring of blood glucose among noninsulin-treated patients with type 2 diabetes in a primary care setting in Hong Kong: A cross-sectional study

Objectives:

The current study aimed to examine the relationship between patient characteristics (internal psychological, external psychological, internal physical, external physical, and educational) and self-monitoring of blood glucose among noninsulin-treated patients with type 2 diabetes in a local primary care setting.

Methods:

This was a cross-sectional study, in which data were collected by a structured questionnaire. Correlational and multivariate multiple regression analyses were performed. Three hundred seventy-four noninsulin-treated patients with type 2 diabetes were eligible and completed the questionnaire in August 2019. The response rate was 93.5%. The respondents’ self-reported self-monitoring of blood glucose adherence was the main outcome measure.

Results:

In predicting self-monitoring of blood glucose adherence, the current regression model accounted for 12.3% of the variance (Adjusted R² = 0.123, p < 0.05), with internal psychological factors and educational factors being significant. External psychological factors, external physical factors, and internal physical factors were found to be statistically nonsignificant.

Conclusion:

The findings highlighted the facilitating role of internal psychological factors and educational factors in SMBG adherence in noninsulin-treated type 2 diabetic patients. Among these factors, the education aspect was relatively strongly associated with increased SMBG adherence. With adequate patient education on diabetes and SMBG, the increased literacy would possibly strengthen patients’ internal psychological factors and motivate them to uptake SMBG practice. Implications from the current findings suggested that further research on different SMBG parameters is warranted to fill the knowledge gap in structuring an individualized and targeted SMBG protocol for better diabetic care.

Health Promoting Self-care Behaviors in Patients With Multiple Sclerosis in the Southeast of Iran: Developing a Model for Practice

INTRODUCTION

Promoting self-care practice, as a critical strategy for enhancing the quality of life in patients with Multiple Sclerosis (MS) is a challenging issue. This study aimed to propose a model of health-promoting self-care behaviors in MS patients.

METHODS

In this cross-sectional study, 200 patients with MS, who had referred to the Hospital for Special Diseases in Kerman City, Iran, were chosen. The main data collection instruments were the multiple sclerosis knowledge questionnaire, the Rosenberg self-esteem scale, multiple sclerosis self-efficacy scale, questionnaire of perceived barriers and benefits of self-care behaviors, social support, the health promotion lifestyle profile II, and resilience and sense of coherence scale. Data analysis was conducted in SPSS V. 22 and AMOS18 software. The Structural Equation Modeling (SEM) was also used for further analysis of data.

RESULTS

The model explained 82% of variance in Health-Promoting self-care Behavior (HPB). The results of the final model obtained from the SEM showed that self-efficacy (β=0.53, SE=0.04, P= 0.007), self-esteem (β=0.39, SE=0.04, P=0.005), social support (β=0.36, SE=0.04, P=0.009), sense of coherence (β=0.34, SE=0.07, P=0.006), resilience (β=0.33, SE=0.07, P=0.018), and perceived benefits (β=0.25, SE=0.05, P=0.009) had a positive and significant relationship with HPB.

CONCLUSION

The self-care empowerment model in patients with MS presented in this study can be used as a framework for designing health promotion interventions to improve the quality of life of patients with MS.

Primary care physician perspectives on barriers and facilitators to self-management of type 2 diabetes

Objectives

To assess physician perspectives on perceived barriers and facilitators to type 2 diabetes self-management (DSM) in a primary care setting.

Methods

The study utilized survey methodology to measure perspectives of primary care physicians on DSM and the challenges they face in managing patients with poor glycaemic stability. Demographic and practice site-related information of the physicians were also collected.

Key findings

Of the 21 physicians who responded (53.8% response rate), 71.2% were aged 50 years or older, 54.2% had ≥25 years of clinical experience, and 50% practiced in an urban setting. The physicians examined 5–60 patients with type 2 diabetes per week (mean = 20), and over 75% of them spent &lt;20 min on face-to-face visits. Approximately, 95% of physicians considered self-care activities such as regular moderate exercise, following a recommended diet, regular blood glucose testing, proper insulin administration and adherence to oral medication as extremely important. Practice-related aspects such as patient–physician communication, patient health literacy and patient follow-up were unanimously considered extremely important, and performance on these measures was rated positively. Interestingly, 66% of physicians felt responsible to some extent for their patient's failure to reach type 2 DSM goals. Physician perceived barriers that contributed to clinical inertia included cost of medications, lack of patient motivation and knowledge, non-compliance with diet and medications, polypharmacy and lack of time and social support.

Conclusions

The study results underscore the importance of DSM in the overall management of type 2 diabetes. Addressing the challenges faced by physicians may result in better self-management and improved clinical outcomes in type 2 diabetes population.

Blood Glucose Monitoring and Its Determinants in Diabetic Patients: A Cross-Sectional Study in Shandong, China

INTRODUCTION

The aim of this study was to explore the status of blood glucose monitoring and its determinants in diabetic patients in Shandong Province, China.

METHODS

This was a cross-sectional survey conducted from 31 August to 12 October 12, in Shandong Province. A multi-stage stratified cluster sampling method was used to select participants. A total of 2183 diabetic patients were included in the analysis. Frequencies and proportions were used to describe the data, and multiple binary logistic regressions were performed to determine factors associated with blood glucose monitoring.

RESULTS

Of the participants, 51.4% tested their blood glucose level more than once a month. The multivariate logistic regression model showed that seven variables were significantly associated with the frequency of blood glucose monitoring: education level, residence, household income, self-reported health, physical examination, anti-diabetic drug or insulin injection, and comorbidity.

CONCLUSIONS

The level of blood glucose monitoring among diabetic patients in Shandong Province is low. Based on these results we recommend that the cost of blood glucose monitoring by professionals in laboratories be reimbursed or at least reduced and that diabetic patients be encouraged to undergo regular physical examinations.

Factors Predicting Sodium Intake of Korean Americans with Type 2 Diabetes

The increasing prevalence of type 2 diabetes mellitus (T2DM) and its complications including cardiovascular disease and chronic kidney disease threaten Korean Americans (KAs). High dietary sodium intake contributes to both conditions. The purpose of the study was to assess dietary sodium consumption and to examine the predictors of sodium intake among KA with T2DM. A total 232 KA who had uncontrolled diabetes participated in this study. The majority of the sample (69%) consumed more sodium than current national guidelines. A high level of energy intake was the strongest predictor for sodium intake with gender and marital status also related. Our findings identified predictive factors to excessive sodium intake and these data support the need for culturally-tailored education about appropriate dietary sodium and energy intake are needed for patients about T2DM.

Barriers and facilitators to diabetes self-management in a primary care setting - Patient perspectives

BACKGROUND

Diabetes self-management (DSM) is a key element in the overall management of type-2 diabetes (T2DM). Identifying barriers and facilitators to DSM and addressing them is a critical step in achieving improved health outcomes in this population.

OBJECTIVE

To assess patient reported barriers and facilitators to self-management of T2DM in a primary care setting.

METHODS

This cross sectional study combined patient survey data with electronic medical record (EMR) data. Patients (age≥18 years) with a recorded diagnosis of T2DM (ICD-9 code: 250. xx) and having ≥2 physician visits were identified from a physician group's EMR database. Patients were grouped based on their A1C levels: <7, 7-9, and >9. Information on demographics, knowledge of diabetes, attitudes, health beliefs, and level of self-management was collected through survey administration. Survey responses were linked to the EMR data, and additional patient information was extracted.

RESULTS

A total of 2100 surveys were administered (700 in each A1C category) of which 210 responses were received (10% response rate). Mean age was 63.7 years ( ±11.79), 108 (51.4%) were males, and 197 (93.8%) were Caucasian. Age (X² = 15.73, p < 0.01), insurance status (X² = 12.03, p < 0.05), referral to an endocrinologist (X² = 6.17, p < 0.05), level of self-management (X² = 12.01, p < 0.05) and willingness to use insulin (X² = 9.8, p < 0.01) were associated with glycemic variability. Level of self-management (X² = 33.04, p < 0.01) and referral to an endocrinologist (X² = 11.11, p < 0.01) were associated with readiness to change DSM behavior. Better self-management, older age, lower willingness to use insulin, and 'less than graduate level' education were significant predictors of glycemic stability.

CONCLUSIONS

Self-management behavior of patients with T2DM is strongly associated with glycemic stability. Interventions directed towards improving self-management in this population may result in improved clinical outcomes.

The effects of health promotion model-based educational program on self-care behaviors in patients undergoing coronary artery bypass grafting in Iran

Background and aim

Post-operative self-care behaviors, have positive effects on increase in adaptability, and reduce cardiac surgery patients’ disability. The present study is carried out aimed at determining the effect of education based on a health promotion model on the patients’ self-care behaviors after coronary artery bypass surgery.

Methods

This is a semi-experimental study carried out in Mazandaran (Iran) in 2016. Two hundred and twenty patients who participated in the study were selected using a simple random sampling method from a population of postoperative patients, and divided into control and experimental groups (110 patients in each) using block (AABB) randomization. Self-designed self-care questionnaires based on a health promotion model were distributed among the patients once before and three months after intervention. The data were analyzed by SPSS-22, Chi-Square tests, Mann-Whitney and ANCOVA at the significance level of p<0.05.

Results

The average score of total self-care behaviors in cardiac surgery patients was not significant between the two groups before education (p=0.065), but after training, a significant difference was observed between the two groups (p<0.001). The analysis of ANOVA with repeated measure indicated that following the intervention, significant difference was observed between the two groups in terms of improvement of self-care behaviors after excluding the effect of pre-test and controlling demographic and health-related characteristics.

Conclusions

Developing and implementing a training program based on the health promotion model can enhance self-care behaviors and reduce the number of admissions in patients after cardiac surgery.

Poor Reliability and Poor Adherence to Self-Monitoring of Blood Glucose Are Common in Women With Gestational Diabetes Mellitus and May Be Associated With Poor Pregnancy Outcomes

OBJECTIVE

To evaluate the compliance with self-monitoring of blood glucose (SMBG) and the reliability of diabetes logbooks in women with gestational diabetes mellitus (GDM), as well as the associated determinants and outcomes.

RESEARCH DESIGN AND METHODS

We prospectively selected French-speaking women with newly diagnosed GDM who had been referred to our diabetes management program and understood SMBG principles. At the next follow-up visit, we collected SMBG results from glucose meters and logbooks. We analyzed pregnancy outcomes.

RESULTS

Data were analyzed over 13 ± 3 days in 91 women. Only 61.5% had performed ≥80% of the required tests. Poor compliance was associated with a family history of diabetes, social deprivation, and non-European origin. The average time between pre- and postprandial tests was 141 ± 20 min, with 46.5% of women performing ≥80% of postprandial measurements 100-140 min after meals. Inadequate timing was associated with ethnicity and higher HbA_1c at baseline. A total of 23.1% of women had <90% matched values in diary and meter memory, and a poor concordance was associated with a family history of diabetes. Poor adherence was associated with more preeclampsia (12.2 vs. 1.9%, P = 0.049), and inadequate postprandial test timing with a higher HbA_1c at delivery (5.3 ± 0.4 vs. 5.0 ± 0.3% [34 ± 2 vs. 31 ± 2 mmol/mol], P < 0.01), despite more frequent insulin therapy.

CONCLUSIONS

Although women with GDM are considered to be highly motivated, SMBG adherence and reliability are of concern and may be associated with poor gestational prognosis, suggesting that caregivers should systematically check the glucose meter memory to improve GDM management.

Lowering Cost Share May Improve Rates of Home Glucose Monitoring Among Patients with Diabetes Using Insulin

BACKGROUND

Not much is known about the extent to which lower cost share for blood glucose strips is associated with persistent filling.

OBJECTIVE

To evaluate the relationship between cost sharing for blood glucose testing strips and continued use of testing strips.

METHODS

This is a retrospective observational study using medical and pharmacy claims data integrated with laboratory hemoglobin A1c (A1c) values for patients using insulin and blood glucose testing strips. Diabetic patients using insulin who had at least 1 fill of blood glucose testing strips between 2010 and 2012 were included. Patients were divided into a low cost-share group (out-of-pocket cost percentage of total testing strip costs over a 1-year period from the initial fill < 20%; n = 3,575) and a high cost-share group (out-of-pocket cost percentage ≥ 20%; n = 3,580). We compared the likelihood of continued testing strip fills after the initial fill between the 2 groups by using modified Poisson regression models.

RESULTS

Patients with low cost share had higher rates of continued testing strip fills compared with those with high cost share (89% vs. 82%, P < 0.001). Lower cost share was associated with greater probability of continued fills (adjusted risk ratio [aRR] = 1.05, 95% CI = 1.03-1.07, P < 0.001). Other patient characteristics associated with continued fills included type 1 diabetes diagnosis, types of insulin regimens, and health insurance plan type. In a subset analysis of patients whose A1c values at baseline were above the target level (8%) set by the National Committee for Quality Assurance guidelines, we saw a slight increase in magnitude of relationship between cost share and continued fills (RR = 1.06, 95% CI = 1.03-1.10, P < 0.01).

CONCLUSIONS

There was a statistically significant association between cost share for testing strips and continued blood glucose self-monitoring. Among patients not achieving A1c control at baseline, there was an increase in the magnitude of relationship. Lowering cost share for testing strips can remove a barrier to persistence in diabetes self-management.

Socioeconomic inequalities in mortality, morbidity and diabetes management for adults with type 1 diabetes: A systematic review

Aims

To systematically review the evidence of socioeconomic inequalities for adults with type 1 diabetes in relation to mortality, morbidity and diabetes management.

Methods

We carried out a systematic search across six relevant databases and included all studies reporting associations between socioeconomic indicators and mortality, morbidity, or diabetes management for adults with type 1 diabetes. Data extraction and quality assessment was undertaken for all included studies. A narrative synthesis was conducted.

Results

A total of 33 studies were identified. Twelve cohort, 19 cross sectional and 2 case control studies met the inclusion criteria. Regardless of healthcare system, low socioeconomic status was associated with poorer outcomes. Following adjustments for other risk factors, socioeconomic status was a statistically significant independent predictor of mortality in 9/10 studies and morbidity in 8/10 studies for adults with type 1 diabetes. There appeared to be an association between low socioeconomic status and some aspects of diabetes management. Although only 3 of 16 studies made adjustments for confounders and other risk factors, poor diabetes management was associated with lower socioeconomic status in 3/3 of these studies.

Conclusions

Low socioeconomic status is associated with higher levels of mortality and morbidity for adults with type 1 diabetes even amongst those with access to a universal healthcare system. The association between low socioeconomic status and diabetes management requires further research given the paucity of evidence and the potential for diabetes management to mitigate the adverse effects of low socioeconomic status.

Self-monitoring of blood glucose among patients with diabetes in Jordan: Perception, adherence, and influential factors

AIMS

To investigate the self-monitoring of blood glucose (SMBG) adherence among Jordanian patients with diabetes and to identify the predictive factors.

METHODS

A cross-sectional survey was carried out in 18 hospitals and healthcare centers covering south, north, and middle of Jordan. All patients with diabetes attending endocrinology clinics from May to December, 2015 were approached. The questionnaires were distributed by trained pharmacists and were self-administered.

RESULTS

A total of 1079 participants completed the survey. Only 59% of participants were SMBG adherent. Predictors of SMBG adherence were treatment regimen; insulin with oral hypoglycemic agents (p=0.044, CI 1.023-5.274, OR=2.323) or insulin only (p=0.005, CI 1.225-3.115, OR=1.953), and health education on how to use the SMBG meter (p<0.001, CI 10.538-32.497, OR=18.506). The frequency of SMBG was significantly associated with the treatment regimen, with patients who were taking oral hypoglycemic agents (p<0.001) or insulin therapy (p=0.004) tested more frequently as compared to others. Additionally, the frequency of testing was significantly associated with the reason of performing SMBG (p<0.001). Frequency of daily testing was the highest among patients who performed SMBG to know if they were hypoglycemic (48.9%) or hyperglycemic (48.0%), or to inform their doctors (28.4%).

CONCLUSIONS

SMBG adherence was suboptimal. Predictors of SMBG adherence were treatment regimen and health education about the SMBG meter.

Mild Visual Impairment and Its Impact on Self-Care Among Older Adults

OBJECTIVE

To determine the prevalence of mild visual impairment (MVI) among urban older adults in primary care settings, and ascertain whether MVI was a risk factor for inadequate performance on self-care health tasks.

METHOD

We used data from a cohort of 900 older adults recruited from primary care clinics. Self-management skills were assessed using the Comprehensive Health Activities Scale, and vision with corrective lenses was assessed with the Snellen. We modeled visual acuity predicting health task performance with linear regression.

RESULTS

Normal vision was associated with better overall health task performance ( p = .004). Individuals with normal vision were more likely to recall health information conveyed via multimedia ( p = .02) and during a spoken encounter ( p = .04), and were more accurate in dosing multi-drug regimens ( p = .05).

DISCUSSION

MVI may challenge the performance of self-care behaviors. Health care systems and clinicians should consider even subtle detriments in visual acuity when designing health information, materials, and devices.

Self-monitoring Blood Glucose (SMBG): Now and the Future

In 2002, the cost of diabetes in the United States reached $132 billion. There is a well-established relationship between blood glucose control and the risk of diabetes-related complications. Tight blood glucose control, through intensive diabetes therapy, reduces the risk and delays the onset of diabetesrelated microvascular complications. Regular and consistent self-monitoring of blood glucose (SMBG) is and should be a part of all diabetes disease state management programs. Pharmacists can truly increase the numbers of patients who use SMBG by being aware and familiar with the monitoring devices available to patients and identifying the physical and psychological issues surrounding SMBG. Results from SMBG and hemoglobin A1C are the basis formost of the medical decisions made for patients with diabetes. This review discusses the best time for patients to test their blood glucose, information regarding blood glucose monitoring devices, alternative site testing, and the newest technology available in glucose monitoring.

Glucometer use and glycemic control among Hispanic patients with diabetes in southern Florida

BACKGROUND

Self-monitoring of blood glucose (SMBG) has been deemed a critical component of diabetes care in the United States. To be effective, patients must have some diabetes knowledge, glucometer proficiency, and an ability to take appropriate actions when certain readings are obtained. However, most patients take no action in response to out-of-range glucometer readings, and in many populations, SMBG practices are not associated with improved glycemic control. Thus, SMBG utilization is being reconsidered in other countries. Nonetheless, SMBG behaviors are increasingly recommended in the United States, where the Hispanic population represents the fastest-growing minority group and is disproportionately affected by suboptimal diabetes outcomes. Because a growing number of interventions aim to reduce diabetes disparities by improving glycemic control among minorities, it is essential to determine whether efforts should focus on SMBG practices. We present data on SMBG behaviors and glycemic control among participants from the Miami Healthy Heart Initiative (MHHI), a National Institutes of Health/National Heart, Lung, and Blood Institute-sponsored trial assessing a community health worker (CHW) intervention among Hispanic patients with poorly controlled diabetes.

OBJECTIVE

This study examined the effects of a CHW intervention on SMBG practices, glycosylated hemoglobin (HbA1c), and knowledge of appropriate responses to glucometer readings among Hispanic patients with diabetes.

METHODS

This study was an ancillary investigation within MHHI, a randomized, controlled trial in 300 Hispanic patients. Participants were intervention-group members who received 12 months of CHW support. Assessments were administered at baseline and poststudy to determine potential barriers to optimal health. Items from validated instruments were used to determine knowledge of appropriate responses to different glucose readings. These data were linked to HbA1c values. Means and frequencies were used to describe population characteristics and glucometer proficiency. Paired-sample t tests examined potential differences in HbA1c outcomes and SMBG practices. Qualitative data were collected from the CHWs who worked with study participants.

RESULTS

Our population was diverse, representing several countries. Mean HbA1c improved significantly, from 10% to 8.8% (P ≤ 0.001). SMBG practices did not change. At baseline, 96% of patients reported owning a glucometer and 94% reported knowing how to use it. However, quantitative assessments and qualitative data suggested that participants had suboptimal knowledge regarding actions that could cause an out-of-range reading or how to respond to certain readings.

CONCLUSIONS

SMBG behaviors were not associated with glycemic control in our sample. We conclude that a CHW intervention may improve glycemic control without improving SMBG practices. Future interventions may reconsider whether efforts should be directed toward improving SMBG behaviors.

The Effect of Blood Glucose Self-Monitoring Among Inmates With Diabetes

The increasing prevalence and risk of complications from diabetes necessitate patient participation and attentiveness to select appropriate foods, perform regular physical activity, and be active in diabetes management and self-maintenance. Diabetes is often largely asymptomatic; consequently, early diagnosis and treatment are necessary. Inmates are a unique population challenged by the increased prevalence of chronic conditions including diabetes. Diabetes standards for inmates contain diagnostic and treatment management guidelines that incorporate personal glucose monitoring for insulin users. In December 2009, the Federal Bureau of Prisons initiated a program to distribute glucose meters to insulin-dependent inmates to facilitate self-monitoring blood glucose. The purpose of this study was to evaluate the effect of these glucose meters on hemoglobin A1c levels.

Effects of eliminating drug caps on racial differences in antidepressant use among dual enrollees with diabetes and depression

PURPOSE

Black patients with diabetes are at greater risk of underuse of antidepressants even when they have equal access to health insurance. This study aimed to evaluate the impact of removing a significant financial barrier to prescription medications (drug caps) on existing black-white disparities in antidepressant treatment rates among patients with diabetes and comorbid depression.

METHODS

We used an interrupted time series with comparison series design and a 5% representative sample of all fee-for-service Medicare and Medicaid dual enrollees to evaluate the removal of drug caps on monthly antidepressant treatment rates. We evaluated the impact of drug cap removal on racial gaps in treatment by modeling the month-to-month white-black difference in use within age strata (younger than 65 years of age or 65 years of age or older). We compared adult dual enrollees with diabetes and comorbid depression living in states with strict drug caps (n = 221) and those without drug caps (n = 1133) before the policy change. Our primary outcome measures were the proportion of patients with any antidepressant use per month and the mean standardized monthly doses (SMDs) of antidepressants per month.

FINDINGS

The removal of drug caps in strict drug cap states was associated with a sudden increase in the proportion of patients treated for depression (4 percentage points; 95% CI, 0.03-0.05, P < 0.0001) and in the intensity of antidepressant use (SMD: 0.05; 95% CI, 0.03-0.07, P < 0.001). Although antidepressant treatment rates increased for both white and black patients, the white-black treatment gap increased immediately after Part D (0.04 percentage points; 95% CI, 0.01-0.08) and grew over time (0.04 percentage points per month; 95% CI, 0.002-0.01; P < 0.001).

IMPLICATIONS

Policies that remove financial barriers to medications may increase depression treatment rates among patients with diabetes overall while exacerbating treatment disparities. Tailored outreach may be needed to address nonfinancial barriers to mental health services use among black patients with diabetes.

Behavioral reactivity to acute stress among Black and White women with type 2 diabetes: The roles of income and racial discrimination

This study investigated relationships of income and self-reported racial discrimination to diabetes health behaviors following an acute stressor. A total of 77 diabetic women (51% Black, 49% White) completed a laboratory public speaking stressor. That evening, participants reported same-day eating, alcohol consumption, and medication adherence; physical activity was measured with actigraphy, and the next morning participants reported sleep quality. Measures were repeated on a counterbalanced control day. There was no mean level difference in health behaviors between stressor and control days. On stressor day, lower income predicted lower physical activity, sleep quality, and medication adherence, and higher racial discrimination predicted more eating and alcohol consumed, even after accounting confounders including race and control day behaviors.

Importance of social support in diabetes care

BACKGROUND AND OBJECTIVES

Diabetes is one of the major concerns in the third millennium, affecting more people every day. The prevalence of this disease in Iran is reported to be high (about 7.7%). The most important method to control this disease and prevent its complications is self-care. According to various studies, this method has not found its proper place among patients with diabetes due to several reasons. The present study was aimed at determining the relationship between social support, especially family support, and self-care behavior of diabetes patients.

MATERIALS AND METHODS

This study was a narrative review in which the relevant papers of cross-sectional, cohort, clinical trial, and systematic review designs were selected using databases and scientific search engines such as PubMed, ProQuest, SCOPUS, and Elsevier, with the keywords diabetes, social support, and self-care. Moreover, Persian papers were selected from MEDLAB and IRANMEDEX databases and through searching the websites of original research papers published in Iran. All the papers published from 1990 to 2011 were reviewed.

RESULTS

The results of the study indicated that the status of self-care and social support in patients with diabetes was not favorable. All the studied papers showed that there was a positive relationship between social support and self-care behavior. Also, some studies pointed to the positive effect of social support, especially family support and more specifically support from the spouse, on controlling blood sugar level and HbA1c.

CONCLUSION

As social support can predict the health promoting behavior, this concept is also capable of predicting self-care behavior of patients with diabetes. Therefore, getting the family members, especially the spouse, involved in self-care behavior can be of significant importance in providing health care to patients with diabetes.

Children's glycemic control: mother's knowledge and socioeconomic status

The present study was designed to examine the role of socioeconomic status (SES) of the mother's knowledge about different aspects of diabetes and the glycemic control of type 1 children with diabetes. Samples were taken from successive admissions to the outpatient diabetes clinics in Prince Sultan Medical Military City (PSMMC), Riyadh, Saudi Arabia. A well designed questionnaire covering different aspects including demographic data, educational background, and socioeconomic status of the care providers was used to collect information from mothers of type 1 diabetes mellitus (T1DM) children. The questionnaire was designed on the basis of the Michigan diabetes knowledge scale and also on the basis of food habits of Saudi Arabia and it was validated. The questionnaire was completed after interviewing the mothers during visits to the PSMMC hospital. Every mother was asked with those particular questions. Glycemic control was assessed by glycosylated haemoglobin (HbA1c). The socio-demographic data of mothers was recorded by self-report. It was found that, there was significant variation in the knowledge of diabetes among mothers with different ages (P 0.05). No significant results were observed between family income and diabetes knowledge (p>0.05).However, a positive relationship was observed with higher income and higher knowledge. There was a significant association between mothers knowledge of diabetes and HbA1C level (r = -0.1739, p.<0.05) indicating that, higher knowledge ultimately leads to greater control of HbA1c level. A significant association was also observed between education and HbA1c level (r=-02538, p<0.05) with children of mothers with higher level of education showing a better control of glycated haemoglobin levels. However, no significant association was found between monthly family income and HbA1C level. In conclusion, the current study illustrated that, mothers with more knowledge of diabetes and with better education were maintaining a better glycemic control of their children, irrespective of the socio-economic status. It was found that, to improve glycemic control and to decrease acute and chronic complications of diabetes in children, mother's knowledge and education is needed.

Review the key role of self-efficacy in diabetes care

INTRODUCTION AND AIMS

Diabetes is one of the chronic and prevalent diseases in the world. Diabetic patients' number has increased 7 times during last 20 years. If this current situation continues, diabetic patients' population will be 350 millions ones in 2030. It means that 7 millions people will be added annually. Up to now, different uncontrollable factors have been monitored in self-caring of this disease for managing and preventing from its early and late side effects. This research is conducted to study the role of self-efficacy as a determinant agent in self-caring of diabetic patients.

STUDY METHOD

This is a narrative review study in which various information banks and search motors such as PubMed, ProQuest, SCOPUS, Elsevier were reviewed. Diabetes, self-care and self efficacy keywords from cross sectional, cohort, clinical experimental studies and systematic review were also used in the study construction. Iranian Banks such as IRANMEDEX, MEDLINE and also different articles from domestic research and scientific magazines were selected. Time spectrum of reviewed studies was supposed to be published from 1990 up to 2011.

RESULTS

Self-care situation among diabetic patients not only is unsatisfactory but also the studies' results show that self-efficacy rate is low among them. The findings of the studies prove that there is a direct relation between self-efficacy and self-care in the patients in a way that this construct owns the predictability power of self-care behavior.

CONCLUSION

Self-caring has a significant role in controlling of diabetes disease. Self-efficacy can induce motivation directly take health promoting behavior through efficacy expectations. It also affects motivation, indirectly, through perceived barriers and determining commitment or stability for following function map. So, self-efficacy is very important in changing self-care behavior process.

Structural role of perceived benefits and barriers to self-care in patients with diabetes

INTRODUCTION AND GOAL

In diseases and disorders such as diabetes, treatment and disease management depends mostly on patient's performance. So, self-care is very important in these patients and they can affect their own welfare, functional capabilities, and disease processes by achieving self-care skills. Nowadays, we know that self care follows individual, psychological and social factors which its recognition can assist health care providing systems to carry out educational programs. This study aimed to investigate the role of perceived benefits and barriers in doing self-care behaviors among diabetic patients.

MATERIALS AND METHODS

This study is a narrative review and articles with sectional, cohort, and interventional, clinical trial, qualitative and narrative designs were chosen using databases and academic search engines such as PubMed, SCOPUS, ProQuest, Elsevier and key words like self-care diabetes, perceived benefits and barriers. Persian articles were also selected using databases like IRANMEDEX, MEDLIB, as well as searching the articles in sites of domestic scientific magazines.

RESULTS

Reviewed articles' findings show the average situation of perceived benefits and barriers in diabetic patients regarding self-care. Qualified blood sugar (glucose) control, weight control, happiness feeling and expenses reduction are the most important perceived benefits. The most significant perceived barriers in self-care consist of lack of family support, shame feeling, forgetfulness and not being able to ignore foods' flavor.

CONCLUSION

Perceived benefits and barriers, as central constructs in some patterns and theories of behavior change, were related to self-care, so that it was directly related to perceived benefits and reversely related to perceived barriers. Therefore, these two constructs can be considered as strategies for promoting self-care behaviors in diabetic patients.

Can health promotion model constructs predict nutritional behavior among diabetic patients?

Since, the nutritional behavior is a complicated process in which various factors play the role, this study aimed at specifying the effective factors in nutritional behavior of diabetic patients based on Health Promotion Model. This paper reviews the published articles from 2000 to the beginning of 2012, using the various data banks and search engines such as PubMed, ProQuest, Scopus, Elsevier, and the key words" perceived benefits and barriers, perceived self-efficacy, social support, activity related affect, situational influences, commitment to plan of action, immediate competing demands and diabetes, self-caring and diabetes. Unfavorable self-care situation especially, inappropriate nutritional behavior is related to some effective modifiable factors. Perceived benefits and self-efficacy regarding behaviors play a major role in the nutritional behaviors. Social support especially, spouses' support has a significant role in this regard. Moreover, there is a reverse relationship between perceived barriers and nutritional self-care. In addition, behavioral feelings, situational influences, commitment to plan of action and immediate competing demands and preferences can also impact and overshadow the nutritional self-care. Following the relationship between constructs of Health Promotion Model and nutritional behavior the constructs of this model can be utilized as the basis for educational intervention among diabetes.

Self-care practices of Chinese individuals with diabetes

The aim of this study was to investigate the self-care practices of Chinese individuals with diabetes. Data were collected from 163 Chinese individuals with diabetes using a one-to-one interview approach. The Chinese version of the Summary of Diabetes Self-Care Activities (SDSCA) was used to assess diabetes-related knowledge and self-care practices. The majority of participants were aware of the importance of self-care in managing diabetes. However, only 70 participants (43%) scored >50% in the diabetes-related questionnaires. Mean fasting blood glucose (FBG) levels were higher (P<0.04) for participants who had extra meals per day (46%). The majority of participants took oral hypoglycemic agents (OHAs; 60.1%) and some were also treated with OHA-insulin combination therapy (17.8%). Participants with medication adherence (52%) tended to have lower FBG levels. Only 13% of participants practiced self-monitoring of blood glucose (SMBG). The predictors of a knowledge deficit or poor self-care were a low level of education (P<0.01) or old age (older than 53 years old; P=0.002). Deficits in diabetes-related knowledge and self-care practices existed among the majority of patients with suboptimal blood glucose control. The understanding of the importance of self-care practices requires improvement in individuals with diabetes. The development of effective education strategies to improve the awareness of self-care practices by Chinese individuals with diabetes is necessary.

Self-monitoring of blood glucose during pregnancy: indications and limitations

Self-monitoring of blood glucose (SMBG) is an important tool to treat diabetes during pregnancy. However, proper implementation of SMBG in pregnant women requires understanding of its applications and limitations. This article reviews issues related to the implementation, efficacy, and accuracy of SMBG and discusses factors that can confound results of SMBG during pregnancy.

"Symptom-based insulin adjustment for glucose normalization" (SIGN) algorithm: a pilot study

BACKGROUND

Lack of self-monitoring of blood glucose (SMBG) records in actual practice settings continues to create therapeutic challenges for clinicians, especially in adjusting insulin therapy. In order to overcome this clinical obstacle, a "Symptom-based Insulin adjustment for Glucose Normalization" (SIGN) algorithm was developed to guide clinicians in caring for patients with uncontrolled type 2 diabetes who have few to no SMBG records. This study examined the clinical outcome and safety of the SIGN algorithm.

SUBJECTS AND METHODS

Glycated hemoglobin (HbA1c), insulin usage, and insulin-related adverse effects of a total of 114 patients with uncontrolled type 2 diabetes who refused to use SMBG or performed SMBG once a day for less than three times per week were studied 3 months prior to the implementation of the algorithm and prospectively at every 3-month interval for a total of 6 months after the algorithm implementation. Patients with type 1 diabetes, nonadherence to diabetes medications, or who were not on insulin therapy at any time during the study period were excluded from this study.

RESULTS

Mean HbA1c improved by 0.29% at 3 months (P = 0.015) and 0.41% at 6 months (P = 0.006) after algorithm implementation. A slight increase in HbA1c was observed when the algorithm was not implemented. There were no major hypoglycemic episodes. The number of minor hypoglycemic episodes was minimal with the majority of the cases due to irregular meal habits.

CONCLUSIONS

The SIGN algorithm appeared to offer a viable and safe approach when managing uncontrolled patients with type 2 diabetes who have few to no SMBG records.

Glucose control in diabetes: the impact of racial differences on monitoring and outcomes

Type 2 diabetes is the seventh leading cause of death in the US and is projected to increase in prevalence globally. Minorities are disproportionately affected by diabetes and data suggest that clinical outcomes consistently fall below American Diabetes Association recommendations. The purpose of this systematic review was to examine ethnic differences in self-monitoring and outcomes in adults with type 2 diabetes. Medline was searched for articles published between January 1990 and January 2012 by means of a reproducible strategy. Inclusion criteria included (1) published in English, (2) targeted African Americans, Hispanic, or Asian adults, ages 18+ years with type 2 diabetes, (3) cross-sectional, cohort, or intervention study, and (4) measured change in glycemic control, BP, lipids, or quality of life by race. Twenty-two papers met the inclusion criteria and were reviewed. Overall, significant racial differences and barriers were found in published studies in diabetes management as it pertains to self-monitoring and outcomes. African Americans tend to consistently exhibit worse outcomes and control when compared to other minority populations and non-Hispanic Whites. In conclusion, significant racial differences and barriers exist in diabetes management as it pertains to self-monitoring and outcomes when compared to non-Hispanic Whites. Explanatory and intervention studies are needed to determine the mechanisms and mediators of these differences and strategies to reduce these disparities. In addition, more research is needed to investigate the impact of racial differences in self-monitoring and outcomes on quality of life.

Impact of individual and environmental socioeconomic status on peritoneal dialysis outcomes: a retrospective multicenter cohort study

OBJECTIVES

We aimed to explore the impacts of individual and environmental socioeconomic status (SES) on the outcome of peritoneal dialysis (PD) in regions with significant SES disparity, through a retrospective multicenter cohort in China.

METHODS

Overall, 2,171 incident patients from seven PD centers were included. Individual SES was evaluated from yearly household income per person and education level. Environmental SES was represented by regional gross domestic product (GDP) per capita and medical resources. Undeveloped regions were defined as those with regional GDP lower than the median. All-cause and cardiovascular death and initial peritonitis were recorded as outcome events.

RESULTS

Poorer PD patients or those who lived in undeveloped areas were younger and less-educated and bore a heavier burden of medical expenses. They had lower hemoglobin and serum albumin at baseline. Low income independently predicted the highest risks for all-cause or cardiovascular death and initial peritonitis compared with medium and high income. The interaction effect between individual education and regional GDP was determined. In undeveloped regions, patients with an elementary school education or lower were at significantly higher risk for all-cause death but not cardiovascular death or initial peritonitis compared with those who attended high school or had a higher diploma. Regional GDP was not associated with any outcome events.

CONCLUSION

Low personal income independently influenced all-cause and cardiovascular death, and initial peritonitis in PD patients. Education level predicted all-cause death only for patients in undeveloped regions. For PD patients in these high risk situations, integrated care before dialysis and well-constructed PD training programs might be helpful.

Consensus report: the current role of self-monitoring of blood glucose in non-insulin-treated type 2 diabetes

The Coalition for Clinical Research--Self-Monitoring of Blood Glucose Scientific Board convened a meeting in San Francisco, CA, July 20-21, 2011, to discuss the current practice of self-monitoring of blood glucose (SMBG) in non-insulin-treated (NIT) type 2 diabetes mellitus (T2DM). Twelve physician panel members from academia, practice, and government attended this meeting. These experts came from the United States, Brazil, Canada, France, Germany, Italy, and the United Kingdom. In addition, three consultants from Australia, Germany, and the United States contributed to the group's final report. This coalition was organized by Diabetes Technology Society. Self-monitoring of blood glucose was studied from eight perspectives related to patients with NIT T2DM: (1) epidemiological studies; (2) randomized controlled trials (RCT)s and meta-analyses; (3) targets, timing, and frequency of SMBG use; (4) incidence and role of SMBG in preventing hypoglycemia with single-drug regimens and combination regimens consisting of antihyperglycemic agents other than secretagogues and insulin; (5) comparison of SMBG with continuous glucose monitoring; (6) technological capabilities and limitations of SMBG; (7) barriers to appropriate use of SMBG; and (8) methods and end points for appropriate future clinical trials. The panel emphasized recent studies, which reflect the current approach for applying this intervention. Among the participants there was consensus that: SMBG is an established practice for patients with NIT T2DM, and to be most effective, it should be performed in a structured format where information obtained from this measurement is used to guide treatment; New, high-quality efficacy data from RCTs have demonstrated efficacy of SMBG in NIT T2DM in trials reported since 2008; Both patients and health care professionals require education on how to respond to the data for SMBG to be effective; and Additional well-defined studies are needed to assess the benefits and costs of SMBG with end points not limited to hemoglobin A1c.

The dynamic interplay between low socioeconomic status and diabetes for urban American Indians

Socioeconomic status is a pervasive predictor of health and has a gradient effect on many diseases, such as diabetes. American Indians and Alaska Natives nationwide live in some of the most difficult socioeconomic conditions and have a higher prevalence of diabetes than any other major racial/ethnic group in the United States. This article contextualizes the nature of socioeconomic status in diabetes, diabetes management, and urban American Indians' lives by using a case study. Underscoring the economic dimensions in this manner can illuminate the complexities of life for urban American Indians with diabetes and guide diabetes initiatives for this population.

Social networks, social capital and chronic illness self-management: a realist review

BACKGROUND

Existing literature on the design of interventions and health policy about self-management have tended to focus on individual-centred definitions of self-care and there is growing recognition of the need to extend consideration beyond individual factors, which determine self-care, to examine wider influences such as the health service, the family and the wider social context.

AIMS

To explore the theoretical and empirical links between social networks, social capital and the self-care practices associated with chronic illness work and management in the context of people's everyday lives.

METHOD

A realist review method was used to search and appraise relevant quantitative and qualitative literature.

FINDINGS

The review findings indicate that social networks play an important part in the management of long-term conditions. We found that social networks tend to be defined narrowly and are primarily used as a way of acknowledging the significance of context. There is insufficient discussion in the literature of the specific types of networks that support or undermine self-care as well as an understanding of the processes involved. This necessitates shifting the emphasis of self-care towards community and network-centred approaches, which may also prove more appropriate for engaging people in socially and economically deprived contexts.

Transition to adult care for youths with diabetes mellitus: findings from a Universal Health Care System

OBJECTIVES

The goals were (1) to describe rates of diabetes mellitus (DM)-related hospitalizations and retinopathy screening before and after transition to adult care and (2) to test whether different methods of transfer of care were associated with improved outcomes.

METHODS

In a retrospective cohort study, we included 1507 young adults with DM of >or=5-year duration and tracked these patients until 20 years of age.

RESULTS

DM-related hospitalization rates increased from 7.6 to 9.5 cases per 100 patient-years in the 2 years after transition to adult care (P = .03). Previous DM-related hospitalizations, lower income, female gender, and living in areas with low physician supply were associated with higher admission rates. With controlling for all other factors, individuals who were transferred to a new allied health care team with no change in physician were 23% less likely (relative risk: 0.23 [95% confidence interval: 0.05-0.79]) to be hospitalized after the transition than were those transferred to a new physician with either a new or no allied health care team. The rates of eye examinations were stable across the transition to adult care (72% vs 70%; P = .06). Female patients, patients with higher income, and patients with previous eye care were more likely to have an eye care visit after transfer.

CONCLUSIONS

During the transition to adult health care, there is increased risk of DM-related hospitalizations, although this may be attenuated in youths for whom there is physician continuity. Eye care visits were not related to transition; however, rates were below evidence-based guideline recommendations.

Frequency and motives of blood glucose self-monitoring in type 1 diabetes

AIMS

Recommendations for self-monitoring of blood glucose (SMBG) from the DCCT have not been implemented with the same rigour as recommendations for intensifying insulin therapy. We assessed the frequency of and motives for SMBG and compared SMBG behaviour with clinical, behavioural and demographic characteristics.

METHODS

Cross-sectional Danish-British multicentre survey of 1076 consecutive patients with type 1 diabetes, who completed a detailed questionnaire on SMBG and related issues. The key variables were test frequency and motive.

RESULTS

SMBG was performed daily by 39% of the patients and less than weekly by 24%. Sixty-seven percent reported to perform routine testing, while the remaining 33% only tested when hypo- or hyperglycaemia was suspected. Age, gender, and level of diabetes-related concern were associated with test pattern. Reported frequencies of mild and severe hypoglycaemia and awareness of hypoglycaemia were independently associated with testing behaviour, whereas the presence of late diabetic complications was not. Lower HbA1c was associated with more frequent testing.

CONCLUSION

Patient compliance regarding SMBG is limited. Thus, almost two thirds of the patients do not perform daily SMBG and one third do not perform routine tests.

Access to care and the incidence of end-stage renal disease due to diabetes

OBJECTIVE

Low socioeconomic status (SES) is associated with an increased risk of end-stage renal disease (ESRD) due to diabetes. Because ESRD is a preventable complication of diabetes, the association with SES may be related to limited access to treatment.

RESEARCH DESIGN AND METHODS

In this population-based ecological study, I examined the association between the incidence of ESRD attributed to diabetes and the proportion of hospitalizations with no insurance, Medicaid, or managed care insurance; residence in a primary care provider shortage area or rural area; and rate of hospitalizations for hyperglycemic complications, by ZIP code in California in 2001-2004.

RESULTS

The incidence of ESRD attributed to diabetes was higher in ZIP codes with higher proportions of hospitalizations with no insurance (r = 0.45; P < 0.0001) or Medicaid (r = 0.69; P < 0.0001) and in ZIP codes with higher rates of hospitalizations for hyperglycemic complications (r = 0.27; P < 0.0001). The incidence was lower in ZIP codes with higher proportions of hospitalizations with managed care insurance (r = -0.37; P < 0.0001) and was lower in primary care provider shortage areas and rural locations. In contrast, there were only weak associations between measures of access to care and the incidence of ESRD attributed to polycystic kidney disease, a condition that is not treatable.

CONCLUSIONS

The incidence of ESRD attributed to diabetes is strongly associated with area-based measures of access to care, suggesting that access to treatment partly mediates the association between SES and the incidence of ESRD.

The accuracy and efficacy of real-time continuous glucose monitoring sensor in patients with type 1 diabetes

BACKGROUND

The accuracy and efficacy of the Medtronic Diabetes (Northridge, CA) Real-Time (RT)-Continuous Glucose Monitoring (CGM) sensor were analyzed in 72 subjects with type 1 diabetes.

METHODS

This was a retrospective analysis of 60,050 temporally paired data points (sensor and glucose meter values) obtained during the course of an outpatient ambulatory study evaluating the efficacy of a sensor-augmented pump system in adults and adolescents. Subjects uploaded sensor values and self-monitoring blood glucose data to the CareLink Clinical Application (Medtronic Diabetes) via the Internet, every 2 weeks during the course of the study.

RESULTS

The overall percentage of sensor readings within +/-20% or +/-30% agreement of reference glucose readings was 75.6% and 86.8%, respectively. The highest rate of agreement occurred in the 240-400 mg/dL range, where 79.9% of sensor readings were within +/-20% of meter values and 91.5% of sensor readings were within 30% of meter values. The mean absolute relative difference for all subjects was 15.8%, and the median absolute relative difference was 10.9%. The bias was -2.13 mg/dL. Paired glucose measurements from the RT-CGM and meter demonstrated that 95.9% of paired points in the overall subject population fell in zones A and B of the Clarke Error Grid. Consensus Error Grid Analysis established that 99.2% of paired data points were in zones A and B.

CONCLUSIONS

This study reports the accuracy of a continuous glucose sensor with a large number of paired data points (60,050). RT-CGM is safe and well tolerated and provides readings that are in close agreement with glucose meter values.

Population-based care of depression: team care approaches to improving outcomes

OBJECTIVE

To describe evidence-based quality improvement interventions in the primary care system that have been shown in randomized trials to the improve quality of care and outcomes of patients with depression.

METHODS

Medical literature review, focused on the concept of population-based care and research-proven ways to decrease the prevalence of depression in primary care, including several meta-analyses that described the effect of collaborative care interventions in improving the quality and outcomes of primary care patients with depression.

RESULTS

A total of 37 randomized trials of collaborative care interventions have shown that collaborative care, compared with usual primary care, is associated with 2-fold increases in antidepressant adherence, improvements in depressive outcomes that last up to 2 to 5 years, increased patient satisfaction with depression care, and improved primary care satisfaction with treating depression. From a health plan perspective, cost-effectiveness analyses suggest that for most depressed primary care patients, collaborative care is associated with a modest increase in medical costs, but markedly improved depression and functional outcomes. The few studies that have used a societal perspective that included examination of both direct and indirect costs found that collaborative care was associated with overall cost savings. For patients with depression and diabetes and depression and panic disorder, there is evidence that the increase in mental health care costs associated with collaborative care is offset by greater savings in medical costs.

CONCLUSION

Collaborative care is a high value intervention associated with improved quality of care, depression outcomes, and improved patient and primary care physician satisfaction.

Self-care practices of Malaysian adults with diabetes and sub-optimal glycaemic control

OBJECTIVE

To investigate the self-care practices of Malaysian adults with diabetes and sub-optimal glycaemic control.

METHODS

Using a one-to-one interviewing approach, data were collected from 126 diabetic adults from four settings. A 75-item questionnaire was used to assess diabetes-related knowledge and self-care practices regarding, diet, medication, physical activity and self-monitoring of blood glucose (SMBG).

RESULTS

Most subjects had received advice on the importance of self-care in the management of their diabetes and recognised its importance. Sixty-seven subjects (53%) scored below 50% in their diabetes-related knowledge. Subjects who consumed more meals per day (80%), or who did not include their regular sweetened food intakes in their daily meal plan (80%), or who were inactive in daily life (54%), had higher mean fasting blood glucose levels (p=0.04). Subjects with medication non-adherence (46%) also tended to have higher fasting blood glucose levels. Only 15% of the subjects practiced SMBG. Predictors of knowledge deficit and poor self-care were low level of education (p = <0.01), older subjects (p=0.04) and Type 2 diabetes subjects on oral anti-hyperglycaemic medication (p = <0.01).

CONCLUSION

There were diabetes-related knowledge deficits and inadequate self-care practices among the majority of diabetic patients with sub-optimal glycaemic control.

PRACTICE IMPLICATIONS

This study should contribute to the development of effective education strategies to promote health for adults with sub-optimal diabetes control.

Primary-care clinician perceptions of racial disparities in diabetes care

BACKGROUND

Primary-care clinicians can play an important role in reducing racial disparities in diabetes care.

OBJECTIVE

The objective of the study is to determine the views of primary-care clinicians regarding racial disparities in diabetes care.

DESIGN

The design of the study is through a survey of primary-care clinicians (response rate = 86%).

PARTICIPANTS

The participants of the study were 115 physicians and 54 nurse practitioners and physician assistants within a multisite group practice in 2007.

MEASUREMENTS AND MAIN RESULTS

We identified sociodemographic characteristics of each clinician's diabetic patient panel. We fit multivariable logistic regression models to identify predictors of supporting the collection of data on patients' race and acknowledging the existence of racial disparities among patients personally treated. Among respondents, 79% supported the collection of data on patients' race. Whereas 88% acknowledged the existence of racial disparities in diabetes care within the U.S. health system, only 40% reported their presence among patients personally treated. Clinicians caring for greater than or equal to 50% minority patients were more likely to support collection of patient race data (adjusted odds ratio [OR] 9.0; 95% confidence interval [CI] 1.2-65.0) and report the presence of racial disparities within their patient panel (adjusted OR 12.0; 95% CI 2.5-57.7). Clinicians were more likely to perceive patient factors than physician or health system factors as mediators of racial disparities; however, most supported interventions such as increasing clinician awareness (84%) and cultural competency training (88%).

CONCLUSIONS

Most primary-care clinicians support the collection of data on patients' race, but increased awareness about racial disparities at the local level is needed as part of a targeted effort to improve health care for minority patients.

CONCLUSION

Collaborative care is a high value intervention associated with improved quality of care, depression outcomes, and improved patient and primary care physician satisfaction.

Effect of cost-sharing changes on self-monitoring of blood glucose

OBJECTIVE

To study the effect of cost-sharing policy changes on utilization of test strips for self-monitoring of blood glucose.

STUDY DESIGN

A legislative mandate (January 1, 2000) required California health plans to cover diabetes supplies, including those for self-monitoring of blood glucose. One health plan, Kaiser Permanente Northern California, initially waived established copayments and provided free test strips to members with diabetes mellitus for 2 years but later instituted a 20% coinsurance charge for a portion of their membership.

METHODS

A retrospective cohort design was used to study pharmacy-based estimates of test strip utilization changes during this natural experiment. Analyses included 2 cohort investigations using pretest-posttest analysis with control subjects to study transitions from a copayment period to a free test strip period and from the free test strip period to a coinsurance period.

RESULTS

During the copayment period, test strip utilization was inversely related to copayments for test strips. Offering free test strips did not increase utilization, even among those paying higher copayments before the policy change. Price-elastic patterns formed before and during the copayment period persisted, despite receiving free test strips for 2 years. The coinsurance, introduced after 2 years of receiving free test strips, resulted in statistically significant (but not clinically relevant) decreased utilization (approximately 1-3 fewer test strips/month). Change patterns did not differ by socioeconomic status.

CONCLUSIONS

Offering free test strips shifted costs from patient to health plan, without improving adherence. The introduced coinsurance slightly reduced utilization and adherence to recommendations about self-monitoring of blood glucose. Neither intervention had marked clinical effect. Cross-sectional analyses should not be used to predict utilization changes in the face of rapidly evolving benefit policies.
